Characteristics of Spatial Evolution and Formation Mechanism of Production-Living-Ecological Space in Heilongjiang Province From 1990 to 2020
Achieving standardized and refined management of production-living-ecological space in Heilongjiang Province is an important foundation for promoting the revitalization and high-quality development of Northeast China.Taking Heilongjiang Province as an example,this paper describes the changes and evolutionary character-istics of the production-living-ecological space pattern in Heilongjiang Province from 1990 to 2020 based on the production-living-ecological space transfer matrix,the dynamic attitude model and the standard deviation ellipse analysis,and discusses the mechanism of the formation of the production-living-ecological space in the study area using RDA analysis.The results of the study show that:① the production space area expands 31721.23 km2 during the study period;the ecological space area decreases and changes strongly,with the loss of green ecological space as the main one.The area decreases by 9.15％,and the living space remains unchanged in general,accounting for 2％of the total area;② The transformation of the production-living-ecological space is mainly in the layout of"one belt and two sides,symmetrical transfer",in which 40751.35 km2 of ecological space has been transformed and 96.56％of which has been changed into production space.The living space is mainly supplemented by the production space,and the transformation of the high-value area is distributed in the northeast of Jiamusi City and Jixi City;③ The scope of the production-living-ecological space is becoming more and more concentrated,and the center of gravity migration is obvious in terms of regional variability and orientation,in addition to other pro-duction spaces and potential ecological spaces with obvious spatial synergistic relationships;④ Natural factors are the key drivers influencing the evolution of the production-living-ecological space patterns,mainly playing a reg-ulatory role in the ecological space,while social factors such as resident population,built-up area and GDP have a strong influence on the production and living space.
